M3 G80 — Stage 2 ECU & TCU Tune
- 79kW power increase over factory output
- Sharper throttle response and engine reactivity
- Harder
- more aggressive transmission shifts
- Enhanced mid-range and high-RPM power delivery
- Improved overall drivability with factory reliability maintained
The S58 responds well to exhaust flow and fresh air. This G80 picked up 79 kW at the wheels after fitting downpipes, midpipes, and a cold air intake, running the Stage 2 BM3 over-the-air map with XHP transmission calibration. Final output sits at 464 kW and 1321.9 Nm at the wheels, both measured on the workshop dyno.
BM3 keeps the process simple for dealers who want a proven off-the-shelf route for competition-spec S58 builds. The XHP file sharpens shift strategy and torque management to suit the extra load. Torque delivery this high wants decent driveline prep and attention to clutch packs if the car sees repeated hard use on track.
Intended for closed-circuit and off-road competition use only.
Is this a custom Protunes file or an OTS map?
This car ran the Stage 2 BM3 over-the-air map paired with XHP TCU calibration. Protunes supplied the file to the workshop; the dyno result reflects the workshop's validation.
What supporting mods are needed for Stage 2 on the G80 M3?
This build used downpipes, midpipes, and a cold air intake. The XHP transmission tune handles torque management for the RWD driveline under the higher load.
What fuel did this car run?
Fuel type was not recorded with the dyno sheet. BM3 Stage 2 maps typically support 98 RON or E85 blends depending on configuration.
